"With V-locity, our SQL batch imports can run during the night so data is ready for production in the morning. Before V-locity, batch jobs would take so long, we would lose a full day of production and sometimes two."
“I’m running the new Diskeeper with Instant Defrag on a Windows 7 server with domain controller, and on Windows 2008 using EqualLogic SAN. These systems run quite a bit faster – especially on VMware. I was quite surprised at that."
"With V-locity, we have delayed investment in additional hardware. We've virtualized servers that used to run on dedicated storage, and now we're using our resources much more efficiently."
“We are running Diskeeper on our Distributed File System server which houses all corporate documents. This server has 500GB of files and was heavily fragmented prior to installing Diskeeper. Users were experiencing latency issues, login delays (roaming profiles) and apps would freeze upon saving to that server. After running Diskeeper there was major performance improvement."
“V-locity is a very valuable tool. I noticed improvement in response time working remotely on a VMware View desktop that was optimized using V-locity. I most enjoy maintaining the defragmented status of our virtual machines so as to decrease access times on machines with many guests running simultaneously. V-locity immediately went to work after installing it on our guest systems. Without touching the product, other than to view a ‘before’ image of the disk utilization, file access times and boot processes were improved within 24 hours and the changes were noticeable to end-users."
“What a brilliant bit of software! If I had known about this Undelete would have been installed long ago. I really am impressed and will certainly spread the word.”
"We’re running SQL Server and extensive backup catalogues. After installing V-locity on our physical servers, we saw over 100% increase in performance throughput.”
“I will absolutely give references for Diskeeper - no problem! We are now running Diskeeper on 15 servers with RAID and SAN as well as with Windows encryption and PGP encryption tools. We are an almost 100% VMware virtual environment. All of our servers are on an EMC CX310 Fiber SAN with 3 RAID arrays. I originally had it set up to manually defrag because I was worried about a performance hit with the automatic mode, but soon found out that it was much easier to use Automatic defrag on all of our servers. We did not experience any performance decreases.”
"We are a large school with nearly one terabyte of data accessed daily, and one-third of that is revised or newly-created. As a network admin, access times and increased throughput are critical to my day-to-day. When my users say, ‘the network seems to be working better,’ I know V-locity is really doing the job.”
“I had two servers that were highly fragmented. One is a file server that has the users My Documents redirected to it and the other is a mail server. I tried the Windows built-in defrag on both servers and had numerous problems. The built-in would literally take days to run and would still not defrag the drives properly. I purchased Diskeeper with Instant Defrag and the results have been great. I can now run a manual defrag on the servers and it is finished within 30 minutes or less. The IntelliWrite and Automatic defrag also help. I will be purchasing more copies for some other servers soon.”
“As you transfer data to a hard drive it cannot take into account that the recorded data will change or the files may become larger. The hard drive will write and store data in pre-determined quantities and fills space based on the table that keeps track of where and how much data exists. The fragments result because files change, become larger, and the space it resides in remains the same due to data stored at its boundaries. The hard drive maintains a record of how the data is stored so if a file had to be extended and could not be appended, the additional data would be stored in a free space area."
"We have found many benefits from using Diskeeper with our Compellent SAN. For a year we were having trouble reclaiming the fragmented files on our servers attached to the Storage Area Network. With Diskeeper we are better equipped to utilize and reclaim unused disk storage on our servers attached to the Compellent SAN. After loading the software on the necessary servers, Diskeeper does all of the work for us. It has reduced the amount of time required by our staff to manage fragmented space on the SAN. Diskeeper also allows us to better achieve ROI for the hardware.”
“File fragmentation had a significant impact on the backup performance of all servers previously identified. Defragging drives on Server1 (both target and source drives) with Diskeeper helped boost throughput by 67%, the average throughput increased from 7MB/s to 11.7MB/s for 5 concurrent drive backups. The longest runtime for any backup job in that group was 10 hours. Defragging the target drives on Server2 increased throughput by 73%, the average throughput increased from 5.9MB/s to 10.2MB/s for 6 concurrent drive backups. The longest runtime for any backup job in that group was = 11.5hrs. Consequently, all tape protection operations ran properly and according to schedules with no data sets missed.”
“If a file was 50 pages long, I would sit and watch the page count loading all 50 pages before printing the report. Some of the files we process are more than 500 pages, so I think you can imagine the pain."
"Case Management Solutions shared with us the pain they were experiencing and the need to find the most cost-effective solution possible. We quickly spotted some necessary server upgrades, but after having seen what V-locity® I/O reduction software had done for our other clients, we knew that was likely the only missing ingredient to tackle their performance issues."
